Question

Salma photocopied the design for a monorail track system. The figure below shows the design and its photocopy.

Two irregular quadrilaterals ABCD and EFGH are drawn. EFGH is the photocopy of design ABCD. AB measures 15 meters, DC measures 17 meters. No dimensions are shown on EFGH.

The ratio of DA : BC is 1 : 2. The total length of track on the design is 47 meters. What is the length, in meters, of side EH on the photocopied image?
